Peritoneal fluid is a liquid that is made in the abdominal cavity to lubricate the surface of the tissue that lines the abdominal wall and pelvic cavity and covers most of the organs in the abdomen. An increased volume of peritoneal fluid is called ascites.
Sampling of peritoneal fluid is generally performed by peritoneocentesis.

Famous quotes containing the word fluid:
“There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.”
—Ralph Waldo Emerson (1803–1882)
